Polar and Paddle both start at 5% + 50¢. Polar's paid plans cut the rate to 3.4% + 30¢, but Paddle never changes. See where each wins by volume and geography.

Paddle’s price sheet has a single row, 5% + 50¢ at any volume, with processing, billing, tax remittance, and chargeback liability all inside it. Polar’s sheet, rewritten in May 2026, is a menu, and the international surcharge splits every option in two.
| Plan | Monthly fee | Domestic rate | International rate | $50 domestic | $50 international |
|---|---|---|---|---|---|
| Paddle | $0 | 5% + 50¢ | 5% + 50¢ | $3.00 | $3.00 |
| Polar Starter | $0 | 5% + 50¢ | 6.5% + 50¢ | $3.00 | $3.75 |

Read down the domestic column and Polar’s paid tiers pull away from Paddle by 70¢, 85¢, and $1.00 per $50 sale. Read down the international column and the 1.5% surcharge hands most of it back.
Pro saves 70¢ per $50 domestic sale against Paddle, so 29 sales (about $1,430 in monthly volume) cover its $20 fee on checkout math alone. Add Polar’s payout charges ($2 a month plus 0.25% and 25¢ per payout, against a USD Paddle payout that converts nothing) and the crossover drifts toward $1,700 and beyond. The same arithmetic lands Growth near $7,000 a month and Scale near $23,000. Past those lines the savings scale. A $50,000 domestic month costs $3,000 in Paddle fees and roughly $2,520 on Scale, plan fee and payout charges included.
Internationally, the entry tiers reverse. A $49 subscription renewal from abroad costs $2.95 on Paddle, $3.69 on Polar Starter, and $3.00 on Polar Pro, which still owes its monthly fee. Pro only underprices Paddle on international charges below a $33 item price, where its smaller fixed fee outweighs the 0.3-point rate deficit. Growth stays under Paddle up to about a $150 price, and Scale at any price. But at a $50 average order, Growth’s 10¢-per-sale edge is thinner than Polar’s own 0.25% payout fee, so a fully international catalog never actually recovers the $100 plan cost unless Paddle’s currency margin also enters the picture.
Take 100 sales at $50 from a US-based seller. With every sale domestic, Paddle takes $300 (6.0% effective), Polar Starter takes $300 at checkout plus about $14 in payout fees, and Polar Pro totals $264 all-in, $36 under Paddle. Now make all 100 sales international. Paddle still takes $300 at checkout, but if buyers paid in local currencies, its 1.5-3% conversion margin claims another $70-140 at payout, for $370-440 total, while Polar Pro lands at $339. The international winner is decided on the payout leg, not at checkout. Local-currency revenue favors Pro, USD-priced international sales favor Paddle.
Three non-rate differences round out the choice. Paddle charges nothing for chargebacks and absorbs the liability, while Polar charges $15 each. Paddle won’t sell items under $10 without a sales conversation. Polar has no floor. And the companies differ in kind. Paddle has operated as a merchant of record for over a decade, while Polar is the open-source entrant whose platform code is publicly readable, and whose pricing, one repricing old, has already made every pre-May-2026 comparison of these two obsolete.
Polar.sh and Paddle aren’t the only two options for this kind of selling. Kelviq, a newer merchant of record, charges 3.5% + 40¢ per sale with no monthly fee (2.9% + 40¢ on your first $5,000). On a $100 domestic sale that works out to $3.90, next to $5.50 on Polar.sh and $5.50 on Paddle, and the fee includes usage metering and entitlements that SaaS and AI products otherwise build separately.
